Local government history and geography Jichitai-shi are one of the materials that take on a signifi cant role in the study of Japanese local history and in regional history education. In recent years, the number of papers attempting to examine the history of these materials has been increasing in the Japanese research community. However, the discussion remains one of the issues facing the project, as it is diffi cult to provide a visually understandable way for the average local history fan to approach Jichitai-shi that they are about to read along with the history of the compilation project. Therefore, the author has been working to overcome these challenges by focusing primarily on the 9 prefectures in the Chugoku-Shikoku region, and publishing a series of papers outlining compilation trends for each prefecture. In this paper, author takes Yamaguchi prefecture as his target area, sets the term “foreign ships (Ikoku-Sen)” from early modern Japanese history as a keyword, and attempts to depict the editorial trends within the prefecture. During the Edo period, Yamaguchi prefecture had the opportunity to deal with ships from Korea, China, and various Western countries. So, this keyword is ideal for explaining compilation trends within Yamaguchi prefecture. As a result of this work, it was found that in Yamaguchi prefecture, there is a correlation between changes in keyword usage and the personal connections of researchers involved in the compilation project. This correlation is more distinct than in other prefectures.
